Marc takes his wife Béatrix and their two children to the seaside house of his youth, but before long the summer holiday begins to fall apart. Nineteen-year-old daughter Laura has a rendez-vous with her biker boyfriend and then heads off to Spain, while their son Charly, 17, is getting suspiciously intimate with another boy. When Béatrix's lover Mathieu shows up, and Marc's old flame appears, complications ensue and the holiday descends into chaos. Acclaimed French actors Gilbert Melki and Jean-Marc Barr head up a cast of comic performers who bring a touch of quirkiness to this summery crowd-pleaser.
